In addition to Web–QoE, we measure the performance of TCP data transmission. As scales for TCP performance evaluation, we adopt three measures: the TCP throughput, the number of retransmission per unit of time and the number of simultaneous connections per unit of time. Here, we define the TCP throughput as the amount of TCP data received by the
Web client per unit of time. The subjects are men or women, and 18–22 years old. The number of subjects is 24
